Basalt Fiber

Basalt is a basalt rock. It is classified as an igneous rock that has been solidified by the cooling of magma and has a mottled structure containing 45% to 52% SiO2 (silicon dioxide).

Basalt fiber is a non-flammable natural material made by crushing the basalt, placing it in a melting furnace, melting it at a high temperature of 1500℃, and then injecting and spinning it. It has excellent fire resistance, acid resistance, alkali resistance, corrosion resistance, and chemical resistance, as well as high strength and high modulus of elasticity. By using Basalt fiber as a reinforcing material, a variety of composite materials can be made with excellent performance.

It is mainly used in construction applications such as reinforcing grids and rods, and it is also used as a substitute for glass fiber due to its alkali resistance, and in recent years, it has been attracting attention as an environmentally friendly material that takes into account the SDGs.

1) The President and the Managing Director have a strong network in China, which enables them to distribute high quality Basalt fibers at lower prices than other companies.

2) We have tried many Basalt fibers from different countries, including those made in Japan, but the quality of Basalt fibres from China, which we deal in, was the best.

3) In addition to the range of Basalt fibers we offer, we can also process any knitting method according to customer requirements.

Basalt cloth is woven with basalt fiber.
It can be woven in a variety of ways, such as plain weave, twill weave, and vermilion weave, depending on the customer’s needs.
Weight and thickness can also be changed depending on the application.

Basalt fibers are uniformly dispersed in a random direction and formed into a sheet using a binding agent.
Excellent choice for hand lay-up molding, filament wiping molding, and compression molding.

It is a thin sheet of finely chopped basalt chopped fiber made by the paper manufacturing method.
It is used to improve the surface finish of the FRP (Fiber Reinforced Plastics) manufacturing process by hand layup molding or press molding, for example, to prevent the surface exposure of glass fiber or basalt fiber.
It is also ideal for manufacturing GRP pipes and storage tanks using the filament winding method.

It is a material with very low thermal conductivity and guaranteed high heat insulation, heat retention, and sound insulation properties that can withstand continuous operation in a wide range of temperature environments from -260°C to over 900°C.

It is a semi-hard product made of high-strength basalt fiber with a coated surface.
It is a good material for reinforcing asphalt and concrete and is suitable for building all kinds of pavements, such as highways, as well as banks and hillsides. Mesh sizes include 5 mm x 5 mm, 10 mm x 10 mm, 25 mm x 25 mm, 40 mm x 40 mm, and 160 mm x 160 mm lattices, etc. Thickness and size can be changed according to customers’ requests and applications.

Basalt Grid is a lattice-like material made of basalt fibers reinforced with resin.
It has higher strength than Basalt mesh and is suitable for reinforcing concrete.
The mesh size is 50mm x 50mm, 100mm x 100mm, 150mm x 150mm, and the thickness is 1mm to 5mm.

Basalt rod is an advanced material that can replace rebar and glass reinforcement and has the complementary advantages of high ductility of rebar and high strength of FRP reinforcement material. There are two types.
(1) Basalt bars, which are reinforced with basalt fibers hardened with resin, are stronger than steel bars and have bending recovery characteristics that allow them to return to their original state without deformation even when subjected to strong loads that would cause steel bars to bend.
(2) Basalt rod material is also available, which is reinforced by wrapping Basalt fiber around the inner core rebar and hardening it with resin and is a low-cost product.
It is available in diameters from 4mm to 25mm, and the length can be cut according to the customer’s requirements.

Experiments on bending recovery characteristics of basalt rods.

This video is a comparison experiment to see what happens when a rebar and basalt rod are bent.
Both rods are bent the same distance using a press.

The reinforcing bar remains bent when it is bent, but the basalt rod has a bending restoration property, so it returns to straightness as before even if it is bent.

Basalt rods are about one-quarter the weight of reinforcing steel bars and have four times the tensile strength of reinforcing steel bars, making them extremely strong and effective for earthquake-resistant reinforcement of buildings.

Basalt insulation board is made from Basalt fiber short-staple fibers using a special process and has excellent heat retention and sound absorption properties, as well as high strength.
It is a fire-resistant insulating material that is ideal for exterior walls and wall cores.

Combustion test of material coated with a solution of next-generation FRP on Basalt insulation.

Basalt fiber can be used continuously in temperatures ranging from -260℃ to 650℃. It is a material that is resistant to very low and high temperatures. Basalt solid board is made by solidifying Basalt fiber with adhesive, so when it is burned with a burner at 1200℃, the adhesive burns and smoke is generated.

In this video, we conduct a combustion test of a nonflammable material that is further insulated by coating Basalt Solid Board with a nonflammable next-generation FRP solution developed by our company.

Even after burning it with a burner at 1200℃ for 10 minutes, it does not burn at all and does not emit smoke. The back side did not reach more than 191℃ after 5 minutes. It is a very good heat insulator in that thinness.

Fire insulating panels are non-combustible insulation materials that sandwich rock wool between basalt insulation boards to enhance the fire insulating effect. It has high tensile and compressive strength and has also five times more durability than organic insulation materials.

Basalt chopped strands are made of long fibers cut into lengths for specific applications.
It is coated with a focusing and binding agent to make it compatible with various materials and ingredients.

Dyeing basalt fiber is very difficult, but this is a prototype of basalt yarn that we dyed red at the customer’s request.
